10 Claims. (01. 229-34) This invention relates to improvements incontainers of the type formed up from a single blank of foldablematerial such as fiber, cardboard, corrugated cardboard, pressboard, andthe like.

The general object of this invention is to provide containers of suchmaterials from a single piece blank folded up so that all of the exposededges of the containers are finished and all joints are fiush.

These and many other objects as will appear from the followingdisclosure are secured by means of this invention.

This invention resides substantially in the combination,construction,arrangement and relative location of parts, all aswill beapparent more fully from the following description.

Figure 8 is a perspective view of a further modified form of containershowing the blank partially folded.

Filing containers comprising cases having slidable drawers are nowfrequently made of a manually foldable material, such as cardboard,corrugated cardboard, fiber, pressboard, and the like. Such filingcabinets are relatively inexpensive and are sufficiently rugged to makethem available for filing away papers and other materials which must bereadily available and yet seldom referred to.

The present invention is related to the drawer of such filing cabinetsalthough the containers of the invention are, of course, not limited tosuch uses. An important object of the invention is the forming of thedrawer from a single piece blank previously scored or creased so thatany one may readily fold the blank up into a strong, rigid drawer orcontainer. Since such drawers are often made of relatively thickcorrugated cardboard, it is desirable to have the exposed edges of thecompleted drawer or container finished. The raw or cut edge ofcorrugated cardboard is rather unsightly, and oneof the objects of thisinvention is to so form and fold the blank that none of the raw edges ofthe blank are exposed. Furthermore, in accordance with this object theblanks of this invention are so folded that all outside faces of thecontainer are smooth and flush or, in other words, none of the edges ofthe blank project above the sides of the container at any:point.

The container of Figures 13, inclusive, is of the type in which thesides are lower than the ends, which is often desirable in a filingcabinet drawer. is illustrated in Figure 3. It is cut from a singlepiece of material which is of generally rectangular form and providedwith scored or creased lines which define the lines of fold. In thedrawings, all edges of the blank are shown in solid lines and all score,crease or fold lines are shown by dotted lines.

The finished blank comprises a central portion l which is the bottom ofthe drawer. It is defined by the fold lines 2, 3, 4 and 5. At 6 and lare the side extensions of the bottom from which the sides of the drawerare formed. At 8 and 9 are the fold lines which extendbetween the apicesof the notched ends 10 of the side extensions.

The outer ends of the sides 6 and I are provided with the tabs I I andI2. The ends of the bottom have integral tabs which consist of theportions I3 and 2| and I1 and 25, respectively. The portion I3 isdefined by the fold lines 2, l4, l5 and IS. The portion 2| is defined bythe fold lines I4, 23, and 24. The flap 28 is defined by the fold line22 and the slots 29. The portion I1 is defined by the fold lines 4, 3,l9 and 20. The portion 25 is defined by the fold lines I8, 26, and 21.The flap 30 is defined by the fold line 30' and the slots 3|. Theportions l3 and 2| and I1 and 25 form the high ends of the drawer, theportions l3 and I1 forming the outer walls of the end and the portions2| to 28 and 25 to 30 forming the inner Walls thereof. The end wallparts are provided with side extensions comprising the parts 50 and 5|separated by the cut or slot 52, portions 53 and 54 separated by theslot 55, portions 32 and 33 separated by the slot 34, and the portions35 and 36 separated by the slot 31. The part 33 is notched at 39 andprovided with a fold line 43, the portion 36 is notched at 4| andprovided with a fold line 45, the portion 50 is notched at 56 andprovided with a fold line 60, and the portion 53 is notched at 58 andprovided with a fold line 66. The portions 32 and 5| and 35 and 54 Theblank of the container of Figure 1 are separated by the sidewall flaps 6and 1, respectively, by a cutter slot that will be apparent from thefigure.

This blank is folded up as indicated in Figure 2 to form the drawer orcontainer of Figure 1. Each end of the blank isfolded over along thefold lines 14 and I8 so that the portions 33, and 36 overlie theportions 32, I1 and 35, respecively, at one end and the correspondingparts overlie at the other end. At each corner the portions 83, 36, 58and 53 are folded on the lines 48, 45, 80 and 82, respectively, so thatthe areas 48, 41, 84 and 88 overlie the areas 48, 48, G5 and 81,respectively. The position of the parts at this stage are shown in thelower right hand corner of Figure 2. The portions 32, 35, 5| and 54 arethen folded along the fold lines 42, 44, GI and 68, respectively. Theextensions of the parts 32, 85, II and 54 then overlie the extensions ofthe parts 88, 88, 90 and 53, respectively. This will be clear fromFigure 2 by observing the upper right hand corner of the container. Theextensions at the end walls are then folded up at right angles .to theend wall, as indicated at the upper right hand corner of Figure 2. Theend walls are then folded up at right angles to the.

bottom, in which case the pairs of overlying extensions will pointtowards each other and stand at the side edges of the bottom I and atright angles thereto, as is clear from Figure 2. The sides 8 and I arethen folded up at right angles to the bottom and the upper portions arethen folded down along the fold lines 8 and 9,- respectively, so as tobecome parallel and encase the extensions of the end walls. The flaps 28and 88 are then folded up on the fold lines 22 and 80', respectively, sothat the tabs H may contact with the inner faces of the portions l3 andI! of the end walls. The flaps are then folded back into place, as isclear from Figure 1. The container is now completely assembled with theparts locked in folded position.

An important feature aside from rigidity and ruggedness of aconstruction of this type is found in the fact that all of the exposededges 8, 6|, I4, 83, 8, 44, I8 and 42 (Figure 1) are finished edges andat no place are the raw edges of the material exposed. Furthermore, thejoints at A on the sides of the container are abutting so that the sidefaces of the container are entirely flush.

In the description of the modification shown in Figure 4, only the partsat one end will be numbered and discussed-since the other end is aduplicate, and in fact this same procedure will be followed out with allthe remaining forms illustrated. In the modification of Figure 4 thecontainer is again made from a one piece blank.. It is cut from arectangular piece along the outline indicated by solid lines and isprovided with fold lines, as indicated by the dotted lines of thedrawings. The bottom is shown at 18 and the side wall at 1| and 1,2. Theend walls consist of the portions 13, I4, l5, I1, 18 and 19. The parts15 and I1 and 18 and 19 are separated by the cut or slot 18 and 80,respectively. The end wall is formed. by folding the flap along thedotted and cut lines so that the portion 14 overlies the portion I3, theportion 11 overlies the portion I5, and the portion 18 overlies theportion 18. The overlying portions 15 and I6 are then folded along thefold lines 8| and 82 which are coincident, and likewise the portions 19and I8 are folded along the overlying fold lines 84 and 83. These doublefold portions are then folded up at right angles to the double thicknessend walls comprising the portions 13 and 14, which in turn are thenfolded up so as to stand at right angles to the bottom 10.

The side walls 1| and 12 are then folded up at right angles to thebottom and then down over the extending portions of the end walls. Theseextending portions of the end walls assume a position which is clearfrom the lower left hand corner of Figure 4. The flaps on the innerwalls of the end walls are then folded up so that the extensions of theside walls can be locked thereunder.

It will be clear from Figure 5 as to the shape of the blank. Theextensions at the end of the bottom walls are folded upon themselves sothat the parts 88 and 81 and 90 and 89 overlie. The parts 89 are thenfolded along the crease lines 9|. The double fold extensions at thesides of the end walls are then bent up at right angles to the endwalls, which in turn are bent up at right angles to the bottom, as isclear from Figure 5. The side walls 85 and 88 are then bent up at rightangles to the bottom and down over the double fold extensions where theyare in this case glued in place to form the finished container. Thiscontainer, as well as that of Figure 4, has finished exposed edges andflat or flush outside faces.

The container of Figures 6 and 7 differs from those previously describedin that the side walls are of the same height as the end walls. Theblank is partially folded as shown in Figure 7. To form the containerfrom this blank the portion 9'|-l00 is folded along the line 98 so that91 overlies 96. This double fold part is now folded along the line 99 sothat the flat contacting parts 98 and 91 move parallel to and inengagement with the portion 95. This gives a triple thickness end wall.The extension beyond the triple thickness formed by the portions 95, 96and 91 are then bent up at right angles to the plane thereof. The triplethickness end wall is then bent up at right angles to the bottom 92. Theextensions at the sides of the end wall then assume the position shownat the left hand end of Figure 7. The side walls 93 are then bent up andover so as to encase this extension. The notches I03 are provided sothat the tabs I02 at the end of the side wall will snap thereinto andlock the parts in place. Here again all exposed edges are finished andthe outer faces of the side walls are flush.

The shape of the blank of the structure of Figure 8 will be clear fromthe drawings. In this case the portions H4--H1 are folded along the lineH6 so that H4 overlies H3 and H1 overlies H8. This double thicknessportion is then folded along the line H5 so that the areas H4, H3 and H2are all parallel and in contact, forming a triple thickness end. Theextension at the side edges of the triple thickness end are then bent upat right angles thereto and the end wall in turn bent up at right anglesto the bottom H0. The position of the parts is clear from the left handend of Figure 8. The side walls I l I are then bent over the extensionsand glued in place so as to encase the extensions and lock the partstogether. Here again all exposed edges are finished and the outer facesof the side walls are fiat.

From the above description it will be apparent that this inventionresides in certain principles of construction and assembly which as willbe clear to those skilled in the art may be varied without departurefrom the scope of the invention. We do not, therefore, desire to bestrictly limited to the disclosure as given for purposes of illustrationbut rather to the scope of the appended cIaims.
